Abstract: 849,988. Filling gas-burning cigarette lighters. COLIBRI LIGHTERS Ltd. June 11, 1959 [Nov. 5, 1958], No. 35564/58. Class 75(3). [Also in Group XXVIII] Filling of a gas burning cigarette lighter from a reservoir is achieved by a screw-threaded neck and socket coupling, both coupling members containing a spring-loaded closure piston, a groove or passage being provided in either the neck or the socket such that as the coupling is screwed or unscrewed, gas from the reservoir escapes. The reservoir is cooled by the escape of gas when the neck is screwed in thereby speeding the filling operation ; the escape when unscrewing prevents overfilling. The spring 15 of the container valve 12 is stronger than the spring 7 of the inlet valve 5 of the reservoir and when the neck 11 is screwed into socket 4, the valve 5 opens first allowing gas to escape along groove 17 in the neck 11. With the neck 11 fully screwed home, sealing washer 9 cuts off the groove 71 and both valves 5, 12 are opened, Fig. 3 (not shown). The groove 17 may be provided on the inner surface of the socket, Figs. 5-7 (not shown) ; or it may be an oblique bore on the neck of the socket Figs. 8 and 9 (not shown). The device may be formed as an adaptor designed either to be fitted to the container or to the reservoir. In Fig. 12, the venting passage 41 is formed in the wall of the socket 4 and is closed by a washer 42 when the neck is screwed home, but when the neck is unscrewed the gas pressure lifts the washer and allows the gas to escape before further unscrewing allows the main valve to close.

Title: Data scanner
IPC: G06F13/34
Filed: 1971-07-30
Abstract: 1313063 Data processing SEARLE MEDIDATA Inc 30 July 1971 [31 July 1970] 35904/71 Heading G4A A data scanner responds to data received from a computer to transmit addresses and commands to a number of stations and simultaneously receives data from the stations; it also decodes interrupt instructions generated by the computer in response to service requests, and includes a manually operable register for entering test data for comparison with data in a monitor register to check for proper transmission of data. In each time slot allocated to a particular station, two words are received from that station and are entered serially into a shift register 24, while at the same time two further words are transmitted to the same station by driver 26. Parallel data exchange takes place between register 24 and buffer 32. A state word from the computer is entered in a register 36 and may indicate an unconditional interrupt or an interrupt which is conditional upon the data from a station and held in buffer 32 indicating that the station requires servicing, i.e. it requires instructions from the computer or has data to transmit to the computer. A station which is requesting service is identified by a clock-driven store counter 57 holding the corresponding slot number, this number being transferred to an interrupt queue table in the computer memory. The numbers of the slots requiring service are removed from this table in the same order as the corresponding stations are serviced. An interrupt queue counter 59 is incremented by each interrupt command and counter 59 provides the address where the slot number in counter 57 is to be stored. Fetch and store counters 58, 57 are one count out of step with each other so that in each time slot two data words are processed for transmission to the corresponding station while two words from the station associated with the preceding time slot are received by the scanner for transmission to the computer. Data flow monitoring.-Switches 52 and 54 are set manually to select two particular time slot s and words therein for transfer from buffer 32 to registers 42, 44 connected to indicator lamp banks 46, 48 so that words transmitted to or from selected stations may be monitored. Various other controls are included for causing display of a word transmitted to the computer by a station only if that station is requesting service, enabling or disabling of the scanner, and testing of the scanner by using an echo shift register 28 to re-cycle the output of register 24 for comparison either in all time slots or only in particular time slots reserved for testing; the words for these time slots being set up on switches.

Abstract: 1431280 Cathode-ray tubes PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 30 July 1973 [2 Aug 1972] 36139/73 Heading H1D [Also in Divisions H3-H5] A device for converting an X-ray image incident at a window 19 to a visible image viewed via a window 18, comprises a transparent electrode 3, a variable birefringent electrooptic plate 1, an electrically insulating layer 4 reflective to the viewing light, e.g. a multilayer dichroic mirror, a photoconductive layer 5 and an electrode 6 transparent to a radiation image which is derived from, or provided by, the X-ray image, and to which layer 5 is sensitive. In use a potential difference is applied between electrodes 3 and 6. In Fig. 2 an X-ray responsive phosphor layer 7 is provided. In variant embodiment, layer 7 may be disposed closely adjacent to electrode 6 but supported separately, Fig. 3 (not shown), a special support or the window 19 may be used or it may be disposed on a fibre optic plate for optical coupling to layers 5 and 6, Fig. 4 (not shown). In Fig. 1 (not shown), layer 5 is itself responsive to X-rays and layer 7 is omitted. In Fig. 6 electrons from a photo-cathode responsive to radiation emitted from an X-ray sensitive phosphor 12 are focused 13 on to a cathodeluminescent phosphor 10. The image therefrom is coupled to layer 5 via a fibre optic plate 9. A metallic layer 14, e.g. of aluminium is deposited on phosphor 10 and may be at the same potential as electrode 6. In both Figs. 2 and 6 the enclosure 21 is evacuated. In Fig. 6 it is separated from the enclosure A by a wall 22 and may be at a somewhat higher pressure relative to enclosure A. In Fig. 5 (not shown), wall 22 and plate 9 are omitted, the phosphor 10 being deposited on electrode 6. In Fig. 7 (not shown), enclosures 21 and A are physically separate, the plate 9 being replaced by two abutting fibre optic plates sealing the ends of the respective enclosures. The birefringent image produced in plate 1 is read out by a polarized light beam which may be coherent. The image is erased by uniformly illuminating photoconductive layer 5 with suitable radiation via either of windows 18 and 19 or by a source within enclosure 21, simultaneously reducing the potential difference between electrodes 3, 6 to zero. Plate 1, e.g. of KDP or KD*P, is at a temperature near its Curie point.

Title: Improved method of hydrogenating coal, oils and similar materials
IPC: C10G1/06
Filed: 1928-12-08
Abstract: 326,238. Tate, W. R., Stephenson, H. P., and Imperial Chemical Industries, Ltd. Dec. 8, 1928. Hydrogenation, destructive.-In apparatus for the destructive hydrogenation of carbonaceous materials, peripheral heating of the reaction space by hot gas is combined with peripheral cooling of the external pressure-resisting walls by cool gas. The gases employed are preferably those taking part in the reaction, and may be circulated in an amount which is a multiple of that required for the reaction. In one form of the invention, Fig. 1, cold hydrogen circulates through a jacket 5 inside a pressure-resisting wall 3 to an external heater 6 where its temperature is raised to 450‹ C.; the gas then passes through a jacket 2 surrounding the reaction space 1, and on leaving at the other end divides into two streams, one passing directly into the reaction space and the other mixing in a preheater 7 with coal, oil &c. from a pressure feed 8. By this mode of operation the temperature gradient rises from the centre of the reaction space to the hot jacket and then falls from the latter to the pressure-resisting wall. In a second form, Fig. 2, the hydrogen passes through a cooling jacket 5, a heat exchanger 9 and heating coil 10 to a heating jacket 2, after which it divides into two streams; one, as before, mixes with the coal, oil &c. in a heater 7 and enters the reaction space; the other is cooled in the heat-exchanger 9 and a coil 11 and is re-circulated through the jacket 5, make-up hydrogen being added at 12.

Filed: 1930-12-03
Abstract: 369,203. Ships' power plant. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and JAKEMAN, R. G., of General Electric Co., Witton, Birmingham. Dec. 3, 1930, No. 36526. [Class 114.] A power plant for ship propulsion comprises a prime mover adapted to drive the propeller non-electrically and an electric motor on the propeller shaft driven by a constant current supplied from a generator driven by an auxiliary prime mover. The main steam or Diesel engine 1 drives the propeller 2, on the shaft 3 of which is an electric motor 5, 6. This motor receives current from the generator 10 driven by a auxiliary steam turbine or Diesel engine 9. The speed of the engine 1 is controlled by the hand-lever 32 but the direction of rotation is controlled by the hand-wheel 36. When the switch 38 contacts with the terminals 42, 43, this wheel also controls the direction of running of the motor 5, 6, through the drum switch 47 .. 56, which reverses the field winding 7, 8, the reverse gear 67 being revolved by the motor 99. With the switch 38 open the wheel 36 controls the engine 1 only and when the switch contacts with the terminals 44, 45, the direction of the motor 5, 6 is controlled only by the hand-wheel 37 acting on the drum switch 57 .. 66. The speed of the engine 9 is controlled by the lever 34 and the field current of the generator 10 by the hand-lever 115. The balancing relay 110 has two opposing coils, 112, 113, the first of which is energized by a small generator 120 driven by the propeller shaft and hence carries a current proportional to the propeller speed. The second coil 113 is in series with resistances controlled by the handles 32, 115 and is across the bus-bars 16, 17, and hence carries a current varied by the position of the speed and current controls of the engines 1, 9. Should the propeller speed exceed a predetermined maximum the contact 111 is opened, the field coil of the generator 10 is de-energized, thus removing the power supply to the motor 5, 6 and decreasing the propeller speed.
